65 * Variant-Formats {OLEAUT32}
68 * When formatting a variant a variety of format strings may be used to generate
69 * different kinds of formatted output. A format string consists of either a named
70 * format, or a user-defined format.
72 * The following named formats are defined:
75 *| General Date Display Date, and time for non-integer values
76 *| Short Date Short date format as defined by locale settings
77 *| Medium Date Medium date format as defined by locale settings
78 *| Long Date Long date format as defined by locale settings
79 *| Short Time Short Time format as defined by locale settings
80 *| Medium Time Medium time format as defined by locale settings
81 *| Long Time Long time format as defined by locale settings
82 *| True/False Localised text of "True" or "False"
83 *| Yes/No Localised text of "Yes" or "No"
84 *| On/Off Localised text of "On" or "Off"
85 *| General Number No thousands separator. No decimal points for integers
86 *| Currency General currency format using localised characters
87 *| Fixed At least one whole and two fractional digits
88 *| Standard Same as 'Fixed', but including decimal separators
89 *| Percent Multiply by 100 and display a trailing '%' character
90 *| Scientific Display with exponent
92 * User-defined formats consist of a combination of tokens and literal
93 * characters. Literal characters are copied unmodified to the formatted
94 * output at the position they occupy in the format string. Any character
95 * that is not recognised as a token is treated as a literal. A literal can
96 * also be specified by preceding it with a backslash character
97 * (e.g. "\L\i\t\e\r\a\l") or enclosing it in double quotes.
99 * A user-defined format can have up to 4 sections, depending on the type of
100 * format. The following table lists sections and their meaning:
101 *| Format Type Sections Meaning
102 *| ----------- -------- -------
103 *| Number 1 Use the same format for all numbers
104 *| Number 2 Use format 1 for positive and 2 for negative numbers
105 *| Number 3 Use format 1 for positive, 2 for zero, and 3
106 *| for negative numbers.
107 *| Number 4 Use format 1 for positive, 2 for zero, 3 for
108 *| negative, and 4 for null numbers.
109 *| String 1 Use the same format for all strings
110 *| String 2 Use format 2 for null and empty strings, otherwise
112 *| Date 1 Use the same format for all dates
114 * The formatting tokens fall into several categories depending on the type
115 * of formatted output. For more information on each type, see
116 * VarFormat-Dates(), VarFormat-Strings() and VarFormat-Numbers().
119 * VarTokenizeFormatString(), VarFormatFromTokens(), VarFormat(),
120 * VarFormatDateTime(), VarFormatNumber(), VarFormatCurrency().
123 /******************************************************************************
124 * VarFormat-Strings {OLEAUT32}
127 * When formatting a variant as a string, it is first converted to a VT_BSTR.
128 * The user-format string defines which characters are copied into which
129 * positions in the output string. Literals may be inserted in the format
130 * string. When creating the formatted string, excess characters in the string
131 * (those not consumed by a token) are appended to the end of the output. If
132 * there are more tokens than characters in the string to format, spaces will
133 * be inserted at the start of the string if the '@' token was used.
135 * By default strings are converted to lowercase, or uppercase if the '>' token
136 * is encountered. This applies to the whole string: it is not possible to
137 * generate a mixed-case output string.
139 * In user-defined string formats, the following tokens are recognised:
142 *| '@' Copy a char from the source, or a space if no chars are left.
143 *| '&' Copy a char from the source, or write nothing if no chars are left.
144 *| '<' Output the whole string as lower-case (the default).
145 *| '>' Output the whole string as upper-case.
146 *| '!' MSDN indicates that this character should cause right-to-left
147 *| copying, however tests show that it is tokenised but not processed.
